average of time

[mystrymaster]

It's been a rather busy day for me so I apologize for the numerous questions.

How do I add time as time? I mean so that 45 seconds + 16 seconds = 1 minute and 1 second not 61 seconds.

and then I would need to average out the total of 8 lengths of time.

Thanks

$t1 = 45;
$t2 = 16;

$total = $t1 + $t2;

echo "Total time is " . floor( $total/60) . " minutes and ". $total%60 . " seconds";

allright that seems to make sense so then how would I do it when the inputs are

10:45 and 15:16?

This is what's known in the trade as "creeping functionallity" when the client keeps moving the goalposts

$t[0] = '10:45';
$t[1] = '15:16';
$total=0;
foreach ($t as time) {
    list ($m,$s) = explode(':', $time);
    $total += $m * 60 + $s;
}
echo "Total is " . floor($total/60)." mins and ". $total%60." secs";

If you have hours:mins:secs, work it out from here.

sorry for that creeping functionality - I thought if I got that I would be able to figure it out however I am just having a dumb day today.

That now makes sense. Thanks to all who helped.
